文章讲述了在编译libwebsockets时遇到关于HMAC_CTX类型错误的问题，解决方法是通过cmake重新编译并指定系统类型为Linux。

报下面的错误：‘HMAC_CTX‘ 的类型不完整

                 from /vagrant/proxy_ws/proxy_lws_utils.hpp:12,

1.遇到这种问题的原因可能是在cmake编译libwebsocket时，没有指定成对应的系统。-DCMAKE_SYSTEM_NAME=Linux

mkdir  build
cd build/
cmake ../-DCMAKE_INSTALL_PREFIX=. -DCMAKE_SYSTEM_NAME=Linux 
make 
make install

2.cmake重新编译，再将.so和.a文件放到指定目录下。

3.再次编译就不会再报 ‘HMAC_CTX‘ 的类型不完整的错误了。
